Tensor renormalization group approach to entanglement entropy
Takahiro Hayazaki, Daisuke Kadoh, Shinji Takeda +1
We propose a method to compute the entanglement entropy (EE) using the tensor renormalization group (TRG) method. The reduced density matrix of a -dimensional quantum system is…

Entanglement entropy by tensor renormalization group approach
Takahiro Hayazaki, Daisuke Kadoh, Shinji Takeda +1
We report on tensor renormalization group calculations of entanglement entropy in one-dimensional quantum systems. The reduced density matrix of a Gibbs state can be represented as…
